Which agent is listed as a water-soluble white powder with no odor?

• A. Phosgene
• B. Cyanide gas
• C. Dushaqiang (TETS)
• D. Blood agents

Answer: (C)

Understanding how chemical agents present themselves helps you recognize them in the field: the physical form, odor, and solubility shape how they’re encountered and detected. Dushaqiang (TETS) is listed as a water-soluble white powder with no odor, which matches a solid that can be disseminated covertly as a powder and then dissolve in moisture to become active. Its lack of odor makes early warning harder, so recognizing this profile is important for hazard recognition and response. Phosgene, by contrast, is largely encountered as a gas at room temperature and has a noticeable odor (often described as a sharp, musty smell), so it doesn’t fit the white powder, odorless profile. Cyanide gas is also typically a gas with its own detectable odor (though not all individuals can smell it), not a water-soluble white powder. Blood agents refer to a class that includes volatile compounds, usually gases or liquids, rather than a solid odorless powder.
